TruDesign Tank Monitor Display Panel 12V – LED Holding Tank Alarm Panel

$39.90
Tax included.

Stay in control of your onboard tank levels with the TruDesign Tank Monitor Display Panel 12V—a simple, reliable LED warning system designed to prevent tank overflows and system failures.

Designed to work seamlessly with TruDesign tank sender switches, this panel provides a clear visual alert when your tank reaches a preset level—typically “full” for holding tanks or “low” for freshwater systems depending on configuration.

The system operates on 12V DC power and features a low-consumption LED circuit, making it ideal for boats, caravans, and off-grid systems where power efficiency matters.

Installation is quick and straightforward, with a compact recessed panel design (approx. 38mm cut-out) and simple wiring—red to positive (via fuse), black to earth, and blue to the sender unit.

Manufactured in New Zealand and built for harsh marine environments, this display panel offers long-term reliability with minimal maintenance, as there are no electrical components exposed to liquid when used with compatible senders.
